摘要
The structure of a new class of dyes, crown ether styryl dyes, is discussed. Quantitative data on trans-cis- and cis-trans-photo-isomerization quantum yields and complexation of the obtained compounds are analyzed. The results on photoinduced and dark complexation of chromogenic 15-crown-5 ether betaine are reported. The formation of an intermolecular coordination bond between a sulfogroup and a metal cation in a crown cavity leading to cis-isomer stabilization has been established.
